Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filament woven or knitted polyester fabric having hygroscopicity and deodorant properties. More specifically, the present invention relates to a polyester filament woven / knitted fabric having excellent composite functions such as hygroscopicity, deodorizing property, antistatic property, and antibacterial property having excellent washing durability.

[0002]

2. Description of the Related Art Generally, polyester fibers are mainly used for work clothes because of their excellent form stability, mechanical strength, chemical resistance, heat resistance, washing durability and the like. However, since polyester fiber has a very low moisture absorption, if it is worn over a long period of time, such as work clothes, it will cause thermal discomfort such as stuffiness and stickiness due to sweating, and sweat and sweat. It is easy to cause odor discomfort such as odor due to bacteria that propagates in the sea. Furthermore, since the electric charge is easily taken and the frictional band voltage is increased, there is a problem that discomfort due to a discharge impact and a trouble to a product are easily caused.

[0003] In such a point, it is inferior to natural fibers and cellulosic synthetic fibers, and in fact, the advance to work clothes applications is partially restricted.

[0004] In order to solve this drawback, for example, Japanese Patent Publication No. Sho 60-475, Japanese Utility Model Publication No. 60-40612,
Alternatively, as described in JP-A-60-215835, it is not possible to obtain moisture-absorbing comfort as a fabric by blending, twisting, or aligning a fiber having a high equilibrium moisture content (moisture absorption) with polyester. Attempts have been made to do so. Although the comfort is certainly improved by using these methods, the effect of eliminating odor discomfort such as odor caused by sweat and bacteria growing in sweat is not sufficient, and when dyeing polyester. In general, there has been a problem that a generally used disperse dye causes contamination, is inferior in color consistency, and loses the physical properties inherent in polyester. Further, the polyester / cotton mixed material tends to be inferior in form stability and abrasion durability as compared with 100% polyester material. In recent years, morphological stability has been improved considerably due to the progress of morphological stabilization technology in recent years, but it is a relatively expensive processing technology due to complicated processes, and some of the hygroscopicity of cotton is impaired by morphological stabilization. Something can be seen.

[0005]

DISCLOSURE OF THE INVENTION The present invention relates to a polyester having the characteristics of morphological stability, strength retention and chemical resistance, which are the characteristics of polyester, as well as excellent hygroscopicity, deodorant and antistatic properties, which are excellent in washing durability. Another object of the present invention is to provide a fabric for clothing which has a complex function such as antibacterial property and a comfortable feeling of wearing, especially a polyester filament woven or knitted fabric for providing a work clothes.

[0006]

The present invention employs the following means in order to solve the above-mentioned problems. That is, in the polyester filament woven or knitted fabric of the present invention, the compound mainly composed of polysulfonic acid is 1 to 20%.
owf and quaternary ammonium salt in 0.02 to 10%
It is made of a polyester woven or knitted fabric provided with owf and has a moisture absorption / desorption parameter (ΔMR) of 1% or more and JIS L-109.
(4) The method is characterized in that the frictional band voltage according to the B method is less than 3 kv, the difference in the increase or decrease in the number of bacteria according to the method for measuring the number of bacteria is 1.6 or more, and the deodorization rate of ammonia is 80% or more.

[0007]

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the deficiency properties of polyester filament woven and knitted fabrics:
When the complex functions such as antistatic property and antibacterial property were studied diligently in a state of excellent washing durability, when a polysulfonic acid compound and a quaternary ammonium salt were simultaneously applied to the filament woven or knitted fabric, such a problem was solved at once. It has been found that it can be improved.

In order to simultaneously cause such a function,
It is important that a specific amount of a polysulfonic acid compound of 1 to 20% owf and a quaternary ammonium salt of 0.02 to 10% owf be given to the polyester filament woven or knitted fabric.

In the present invention, the polyester woven or knitted fabric is not limited to 100% polyester, but may be any fabric such as a woven fabric using a mixed fiber of polyester and natural fibers or cellulose-based synthetic fibers, or a woven fabric woven with natural fibers or cellulose-based synthetic fibers. It is not limited.

In the present invention, the compound mainly composed of polysulfonic acid means a compound obtained by copolymerizing vinyl sulfonic acid and a crosslinking agent. Specific examples of vinyl sulfonic acid include 2-acrylamido-2-methylpropane sulfonic acid, 2-alioxy-2-hydroxypropane sulfonic acid, sodium styrene sulfonate, sodium sosoprene sulfonate, sulfoethyl methacrylate, sodium allyl sulfonate, Sodium methallylsulfonate can be used. In the present invention, two or more of these monomers may be used without any problem. It is particularly preferable to use 2-acrylamido-2-methylpropanesulfonic acid from the viewpoints of polymerization efficiency and hygroscopicity.

The crosslinking agent is not particularly limited, but it is preferable to use a divinyl monomer or a vinyl monomer having a methylol group. For example, N-methylolacrylamide or N-methylolmethacrylamide is preferably used. Particularly preferred are polyethylene glycol diacrylates represented by the general formula [I].

[0012]

Embedded image (Here, X represents H or CH ₃ , and m represents 1 to 23.) From the viewpoint of imparting excellent texture and hygroscopicity, such a compound containing polysulfonic acid as a main component has an owf of preferably 1 to 20%. It adheres to the fiber in the range of 3 to 10% owf. If it is less than 1% owf, there is a problem that sufficient hygroscopicity cannot be imparted, and if it exceeds 20% owf, the hand becomes coarse and hard, and it is not suitable as work clothes.

The quaternary ammonium salt used in the present invention can be used without any particular limitation as long as it is a compound capable of imparting antistatic properties and antibacterial properties. Preferably, the compounds are represented by the following general formulas [II] and [III]. And at least one selected from [IV], and particularly preferably,
When at least the quaternary ammonium salt represented by the general formula [IV] is contained, excellent antistatic properties, antibacterial properties and durability can be imparted.

Embedded image (Where R ₁ is an alkyl group having 6 to 20 carbon atoms, R ₂ is an alkyl group having 1 or 2 carbon atoms, and R ₃ is an alkyl group having 1 or 2 carbon atoms.
R ₄ is an alkyl group having 1 or 2 carbon atoms,
R ₅ represents H or CH ₃ , and n represents 1 or 2. ) Among the quaternary ammonium salts represented by the above formula [IV], R ₁ has 6 to 6 carbon atoms such as octyl, nonyl, decyl, dodecyl, tetradecyl, pentadecyl and octadecyl.
The alkyl group having 20 carbon atoms is preferable, the alkyl group having 8 to 18 carbon atoms is more preferable, and the alkyl group having 10 to 12 carbon atoms is more preferable. If the number of carbon atoms is 5 or less or 21 or more, the antibacterial activity tends to be insufficient.

Preferably, R ₂ , R ₃ and R ₄ are each independently a methyl or ethyl alkyl group having 1 or 2 carbon atoms. When the number of carbon atoms is 3 or more, the viscosity tends to increase, which tends to be unfavorable in production, and the solubility in water decreases. On the other hand, when the number of carbon atoms is 0, that is, in the case of H, it becomes ammonia gas and is not an ammonium salt. R ₅ is H or CH _{3. When the} number of carbon atoms is 2 or more, the viscosity tends to increase, which tends to be unfavorable in production, and the solubility in water decreases. n is preferably 1 or 2. That is, a phosphorus atom is pentavalent, of which divalent is occupied by oxygen, and the remaining trivalent is shared by a hydroxyl group and a specific organic group having a double bond in the formula. When n is 0, the anion becomes a phosphate ion and the functional group containing a double bond disappears, so that radical polymerization hardly occurs and durability tends to be lost. On the other hand, when n is 3, the hydroxyl group bonded to the phosphorus atom is lost and the quaternary ammonium salt is not used, so that the antistatic performance and the antibacterial performance tend to be significantly reduced.

The quaternary ammonium salt is preferably used in an amount of 0.02 from the viewpoint of imparting excellent texture and hygroscopicity.
It is good to be fixed to the fiber in the range of 10 to 10% owf, more preferably 0.05 to 2% owf.

As a method for fixing the compound mainly composed of polysulfonic acid and the quaternary ammonium salt to the fiber, a method in which the polysulfonic acid and the quaternary ammonium salt are simultaneously fixed by a single-step treatment, or
A method in which a polysulfonic acid is first fixed and then a quaternary ammonium salt is fixed in a two-stage treatment, or
In the step treatment method, such as the one in which the fixing compound is reversed,
Either method can be used.

In the present invention, as a specific method for fixing the compound mainly composed of polysulfonic acid and the quaternary ammonium salt to the fiber, any means can be used as long as it is a method used for radical polymerization. For example, a dry heat treatment, a steam treatment, a dipping method, a cold batch method, a microwave treatment, an ultraviolet treatment, or the like can be used. These means may be applied alone, or may be combined with, for example, microwave treatment or ultraviolet treatment at the time of steam treatment or dry heat treatment in order to increase the heating efficiency. In the presence of oxygen in the air, polymerization becomes difficult to proceed, so dry heat treatment, microwave treatment,
In the case of ultraviolet treatment, the treatment is preferably performed in an inert gas atmosphere, and also in the case of the cold batch method, it is preferable to seal with a sealant.

Among these radical polymerization methods, steam treatment is preferred from the viewpoint of polymerization efficiency and treatment stability. Steam processing includes normal pressure steam, overheated steam,
High-pressure steam may be used, but from the viewpoint of cost, normal-pressure steam and superheated steam are preferred. The steaming temperature is preferably 80 to 180 ° C, more preferably 1 to 180 ° C.
00-150 ° C. Steam processing time is 1-10
Minutes. In the present invention, before the monomer is polymerized, air drying or preliminary drying with a dryer may be used.

As the polymerization initiator used in the present invention, a usual radical polymerization initiator can be used. For example, inorganic polymerization initiators such as ammonium persulfate, potassium persulfate, and hydrogen peroxide; 2,2'-3 azobis (2-amidinopropane) dihydrochloride; and 2,2'-3 azobis (N, N Organic polymerization initiators such as' -dimethyleneisobutyramidin) dihydrochloride and 2- (carbamoylazo) isobutylnitrile can be used.
Further, a water-insoluble polymerization initiator such as benzoyl peroxide and azobisisobutylnitrile may be used after being emulsified with a surfactant such as an anion or a nonion. Ammonium persulfate is preferably used in terms of cost and ease of handling. Further, in order to increase the polymerization efficiency, a so-called redox polymerization initiator using a peroxide and a reducing substance together as a polymerization initiator may be used. Further, in the present invention, as a method of fixing the compound mainly composed of polysulfonic acid and the quaternary ammonium salt, a method of fixing with a binder or the like in addition to the above-described copolymerization of the monomer can also be adopted. The binder is not particularly limited, but among them, acrylate resin, polyurethane resin, melamine resin, polyetherester block copolymer, polyamide resin, silicone resin and the like are preferable. Among these binders, silicone resins are preferable because they improve washing durability and flexibility of clothing. Among such silicone resins, 8

The polyester filament woven or knitted fabric of the present invention provides a garment fabric that is comfortable to wear when only such a structure, that is, a compound mainly composed of polysulfonic acid and a quaternary ammonium salt are fixed to the woven or knitted fabric. I can't. That is, it is indispensable that such a compound is fixedly possessed, but it is essential that the woven or knitted fabric simultaneously satisfies the following four functions. That is, (A) the moisture absorption / desorption parameter (ΔMR) is 1% or more.

(B) The friction band voltage according to JIS L-1094 B method is less than 3 kv.

(C) The difference in the increase or decrease in the number of bacteria according to the method for measuring the number of bacteria is 1.
6 or more.

(D) The deodorizing rate of ammonia is 80% or more.

All of the above-mentioned problems can be solved only by the polyester filament woven or knitted fabric having such specific functional characteristics.

First, the above moisture absorption / desorption parameters (ΔM
If R) is less than 1%, the moisture absorption rate is low, and it is difficult to prevent stuffiness and stickiness due to sweat from the skin. Is preferably 3% or more from the viewpoint of comfort when worn. This moisture absorption / desorption parameter (△ M
The upper limit of R) is not particularly limited, but is preferably 10% or less, and more preferably 7% or less, in consideration of the feeling. Regarding the hygroscopicity, it is preferable to have excellent washing durability. Specifically, the hygroscopic parameter (ΔMR) after washing 30 times is preferably 50% or less before washing, more preferably 80%. %.

The moisture absorption / desorption parameter (ΔMR) is defined as the moisture absorption rate (MR ₂ ) at 30 ° C. × 90% RH and 2
A value (ΔMR (%) = MR ₂ −MR ₁ ) expressed as a difference from the moisture absorption (MR ₁ ) at 0 ° C. × 65% RH.

Here, ΔMR is a driving force for obtaining comfort by releasing moisture in the clothes when the clothes are worn to the outside air, and is used when light to medium work or light to medium exercise is performed. It represents the difference in moisture absorption between clothing temperature and humidity represented by 30 ° C. × 90% RH and external temperature and humidity represented by 20 ° C. × 65% RH.

In the present invention, this ΔMR is used as a parameter as a scale for evaluating hygroscopicity. Δ The larger the MR, the higher the moisture absorption / release power, indicating that the comfort during wearing is better.

Next, in the case of the conventional polyester filament woven or knitted fabric, the antistatic effect of the conventional polyester filament woven or knitted fabric tends to decrease with respect to the frictional electrostatic potential according to the JIS L-1094B method (frictional electrical potential measurement method). However, in the polyester filament woven or knitted fabric of the present invention, unless the friction band voltage after washing 30 times is less than 3 kv, the comfort at the time of wearing cannot be satisfied. Here, one wash means that 25 liters of a 0.2% slightly alkaline synthetic detergent solution of 40 ± 2 ° C. is put into a washing tub of a commercially available automatic vortex electric washing machine,
After adjusting so that the total weight of the test cloth and the additional cloth becomes 500 g quickly, the washing is performed in a procedure of 5 minutes, dehydration 30 seconds, rinsing 2 minutes, dehydration 30 seconds, rinsing 2 minutes, and dehydration 30 seconds. . In addition, rinsing is performed while overflowing using room temperature water. The more preferable value of the triboelectric voltage after 30 washes of the polyester filament woven or knitted fabric of the present invention is preferably less than 1 kv (substantially 0 kv) from the viewpoint of durability against washing.

Next, when the difference in the increase or decrease in the number of bacteria according to the method for measuring the number of bacteria in the antibacterial evaluation method (according to AATCC-100-1977) used by the Textile Sanitation Processing Council is less than 1.6, the polyester is used. The problem that the antibacterial property of the filament woven or knitted fabric is low and the antibacterial and deodorant effects are low is caused.

Further, the deodorizing rate of ammonia is preferably substantially within the range of 80 to 100%. If the deodorization rate of ammonia is less than 80%, there arises a problem that the effect of completely absorbing the odor of sweat is lacking. The measuring method will be described later in the examples section.

The polyester filament woven or knitted fabric of the present invention is characterized in that the above-mentioned compound mainly composed of polysulfonic acid and
In addition to the structure in which the quaternary ammonium salt is fixed to the woven or knitted fabric, the above-mentioned function is superimposed, so that it is possible to provide a comfortable clothing fabric having an excellent wearing feeling.

In the woven or knitted polyester filament of the present invention, first, the woven fabric has a weft density of 50 to 250 threads / inch for each of the warp and the weft, and at least one of the warp and the weft has a single yarn fineness. 0.1 to 10 denier, using a yarn with a total fineness of 75 to 350 denier, furthermore, from the viewpoint of maintaining the strength as a garment fabric, particularly work clothes, in such a woven fabric, at least one of the warp and the weft, The woven fabric preferably has a tear strength of 1000 g or more.

The warp and weft density of the woven fabric is 50
If it is less than books / inch, seam misalignment or eye misalignment during wearing tends to occur. On the other hand, if the weaving density of the warp and weft exceeds 250 yarns / inch, the woven fabric tends to be thick and coarse, and the lightweight feel tends to be impaired.

If the single yarn fineness of at least one of the warp and the weft is greater than 10 denier, the texture of the woven fabric becomes hard, and it becomes difficult to use. Further, from the viewpoints of weaving and holding strength, the single-fiber fineness is preferably 0.5 denier or more. As the warp and / or weft, a mixed yarn of different fineness filament yarns having different single finenesses may be used, which is preferable from the viewpoint of producing a soft and firm fabric.

If the total fineness of at least one of the warp and the weft is less than 75 denier, the fabric tends to be thin without tension. On the other hand, the total fineness is 350
If it is larger than denier, it becomes a fabric having a ground thickness and a hard texture, which makes it difficult to use.

As the structure of such a woven fabric, a woven fabric having a structure such as a flat structure, a twill structure, a satin structure and a change structure thereof can be used, but is not limited to such a woven structure.

Next, as for the knitted fabric of the polyester woven or knitted fabric of the present invention, a warp knitted fabric is preferably used, and the density of the warp knitted fabric is 18 to 40 wells / inch in the well direction.
The course direction is 30 to 70 courses / inch, and at least one of the front, middle, and back yarns has a single yarn fineness of 0.1 to 20 denier and a total fineness of 15 to 15
A yarn having a denier of 350 kg or more and a burst strength of 5 kg or more is preferably used. If the density of the warp knitted fabric is less than 18 wells / inch and / or 30 courses, the rupture strength of the fabric is low, the fabric becomes thin, and the texture becomes too soft for a garment fabric, especially a work clothes fabric. On the other hand, if the density is 40 wells / inch and / or 7
If it exceeds 0 course / inch, the fabric becomes thick, the air permeability becomes poor, and the lightness tends to be impaired.

Further, when the fineness of the single yarn is too small, the yarn is liable to break, the broken single yarn comes off the guide, and a quality defect such as a thread occurs, and the knitting machine must be stopped each time. Becomes difficult and productivity is remarkably reduced. The knitting yarn constituting the knitted fabric of the present invention is preferably 0.1
A fiber having a single denier of at least denier or more, more preferably at least 0.5 denier, is used from the viewpoint of knitting properties and the strength of the fabric, and the knitting yarn is mixed with filaments of different deniers having different single deniers. If it is composed of yarn or the like, a soft and firm warp knitted fabric can be created.

When the total fineness of the yarn is less than 15 denier, knitting difficulty increases, defects such as yarn breakage are liable to occur, and the strength of the fabric tends to decrease.
Preferably, the knitting yarn has a total fineness of 20 denier or more. On the other hand, if the total fineness is greater than 350 denier, needle breakage is apt to occur during knitting, which causes defects such as holes in the greige machine, and reduces productivity.
In addition, the knitted fabric becomes thick and has a hard feeling, and it is difficult to use the knitted fabric. Further, if the rupture strength of the cloth is less than 5 kg, it is not possible to maintain the strength to withstand use.

As such a polyester filament warp knitted fabric, those having a structure such as a half, an inverted half, a satin and a change structure thereof, a tricot fabric, a Russell fabric and the like can be used. Absent.

The tear strength, burst strength, deodorant property, and texture were measured by the following methods.

(Tear strength) JIS L-1096
Method D (Pendulum method) (burst strength B) JIS L-1018A method (deodorant) Deodorant was evaluated by deodorant rate. 5 g each of 3 g of the sample and 4 large odor gases having the concentrations shown in Table 1 below
After placing in a 00 ml washing bottle and leaving it for the time shown in Table 1 below, the residual gas concentration was measured, and the deodorizing rate was calculated by the following equation.
